port install wxgtk +opengl fails

[t.koziara@…]

It seems like there issues with linking the compiled objects. See:

OK, here is the fix that worked for me:

I edited directly the Makefile in

/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_x11_wxgtk/work/wxGTK-2.8.11

by adding "-L/opt/local/lib/ -lg" at the end of this line

EXTRALIBS =  -L/opt/local/lib -arch i386  -L/usr/X11R6/lib  -framework IOKit -framework CoreServices -framework System -framework ApplicationServices  -lz -lpthread -liconv -L/opt/local/lib/ -lg

Somebody who is into autoconf & automake stuff might like to add suitable patch.

[justin.ales@…]

patch for compilation of opengl variant

[justin.ales@…]

-lg did not work for me

but:

-lgl did work for me

I attached a patchfor the Portfile that adds: configure.ldflags-append -lgl

to the opengl variant settings

Cc Me!
